Bluestar 185, amps wont adjust

01-19-2013, 10:57 PM

Maybe its common, and an easy fix (so I hope). I have a blue star 185, that runs great. Problem is that it welds wide open (180+ amps) all of the time. It will not adjust. I have tested the rheostat and it seems to check out fine. Should I just replace it? Any one have any ideas? Can I get one from an appliance store, or does it have to be from miller? Has anyone else had this problem? I'll post serial # when I get home tomorrow.
Thanks

Well, if anyone is following this, the problem ended up being the pc1 board. Miller wanted $4xx for a new board. I could get one from y supplier for $3xx. I found a guy in Miami that rebuilds them, he rebuilt it for $150!!!!! Got it back today, welder fired right up, and adjusted perfectly. All is well again. Im gonna send him the board for the other machine next week. PROBLEM SOLVED!!!!!
